Brenspeed Stage 2 Saleen Supercharger - need your advice!

Hello,

Please help me with supercharger. I am strongly considering that power mod. I am from Europe so I am definitely looking for turn key kit simply to install and then simply to maintenance.

After searching and some reading I think I will go with Brenspeed Stage 2 Saleen Package 485 HP
http://www.brenspeed.com/saleenstage2.html

Is that a good choice? What is your opinion? What is your experience with that package or Saleen supercharger?


And now what further I need to modify in my stock engine to handle new power and to maximum protect it against possible damage.

My chaotic list is:

1/ Mustang GT Spec Clutch Stage 2+ from Brenspeed (http://www.brenspeed.com/sf463h.html)
2/ Mustang GT Spec Aluminum Flywheel from Brenspeed (http://www.brenspeed.com/sf46a.html)
3/ Brisk one piece Spark Plugs
4/ Mustang GT Heat Exchanger For Saleen (http://www.brenspeed.com/555-3706.html) Is there any come with Brenspeed Stage 2 package?
5/ Oil Cooler Kit by Cobalt (http://www.mossmustang.com/Shop/View...eIndexID=53829)
6/ MMR 7 Quart High Performance Oil Pan (http://www.modularmustangracing.com/)
7/ MMR Performance Windage Tray
8/ Aeroforce Interceptor Gauges - Double Gauge (http://www.steeda.com/products/aerof...ble_gauges.php)
9/ Aeroforce Boost Sensor Kit

That’s it for now.
What would you remove and what would you add to that list?
What about improving fuel delivery or offered in Stage 2 Kit the Vacuum line kit is enough?

Looking forward your opinion and advice

There are many on here that can answer your questions as to the final product, but I can say that I've done some extensive research, along with the help of others on here, and while I would have liked to have gone Stage 3, my Stage 2 is being delivered as we speak.

The only things I will be going with initially is a set of gauges, a wideband a/f is first on the list, along with boost and fuel pressure. I have a similar "chaotic list" in my head as well, but I think I'll tackle those mods as they become necessary since I'm not sure what I'll find becomes the weak link in my stock parts first.

I'm going to be doing the install myself, and I have to say along with the words of encouragement from others on here, the fact that Brent does such a great job with SCT tunes for these packages and that they do these installs all the time, having the quality support that they offer made me alot more comfortable about taking the project on.

I think it's a great package, and I'm sure you'd be happy with it, but you will get some more in-depth information from the guys that have been running them for a while now.

Good luck with your decision!

2/ Mustang GT Spec Aluminum Flywheel from Brenspeed (http://www.brenspeed.com/sf46a.html)
Unless your clutch is slipping there is no need at this time
3/ Brisk one piece Spark Plugs
Go with the Autolite HT0
4/ Mustang GT Heat Exchanger For Saleen (http://www.brenspeed.com/555-3706.html) Is there any come with Brenspeed Stage 2 package?
It does come with the stock size Saleen H.E.
5/ Oil Cooler Kit by Cobalt (http://www.mossmustang.com/Shop/View...eIndexID=53829)
I believe there is one already on a stock Mustang that works well
6/ MMR 7 Quart High Performance Oil Pan (http://www.modularmustangracing.com/)
7/ MMR Performance Windage Tray
Again the stock one performs well
8/ Aeroforce Interceptor Gauges - Double Gauge (http://www.steeda.com/products/aerof...ble_gauges.php)
9/ Aeroforce Boost Sensor Kit
These are good gauges plus get a wideband A/F
I would look into a better fuel system, at the very less get the KB BAP. The GT500 twin pump is better and if you are going to go fast look for better brakes to stop

That’s it for now.
What would you remove and what would you add to that list?

Thanks for your suggestions. Some other points after that short discussion.
1/ 'DLY' Can you put or any one can put some link for a good wideband A/F. I was pretty sure that Aeroforce Interceptor Gauges I am planning will cover that A/F measure.
2/ Does any one have a picture showing all components of Saleed Brend Speed Stage 2 kit I would like to see how that Intercooler in a kit look like.
3/ As far as I am aware there is no any Oil Cooling Kit in a stock Mustang GT.
3/ KB Boost a Pump - ok I put that on my list
4/ Autolite HT0 - I do not like the 2 pcs spark plugs - what is wrong with Brisk?
5/ I have sent e-mail to Brenspeed as well - weak ago and yesterday – no answer but maybe they are busy with new website – That would be nice to se someone of them here
6/ What fuel use Brenspeed Saleen Stage 2 Kit – 91 octane or 93 octane?
7/ Will I need Driveshaft Loop Kit like this one for example (http://www.fordracingparts.com/parts...tKeyField=8082)

Here's a couple things that you could look into.

What octane is available where you are?

Give some thought to adding beef to the bottom end, particularly some forged rods.

Well I haven't had much time to process your list but a couple of thngs come to mind......

1) As suggested, I would add the Kenne Bell BAP just for extra insurance...... but you could talk to Brent or Dave about it directly. Seth would know too. I ran the BAP for about a year with no problems, but since have replaced it with the GT500 fuel system.

2) Aeroforce guages- I love mine. You mentioned getting their boost kit, good idea. They are also supposedly coming out with an air/fuel kit later this year too, so I would just do that instead of buying a dedicated third guage. Go with an SOS (Speed of Sound) pillar pod.

3) Clutch- your factory clutch may last a long time, or it may not. Just depends on your driving habits, etc. You mention the Spec 2+, that is a good choice however if you research I think you'll find that most people are opting for the 3+. I myself am doing the 3+ along with a steel flywheel next week. More importantly, and this is not on their website yet- when you do the clutch install, get yourself an adjustable, hydraulic throw-out bearing from RAM. You can ask Brenspeed about this or you can order one from www.lethalperformance.com. This is critical to making an aftermarket clutch in these cars perform flawlessly, atleast in my opinion. Go to www.modularfords.com and search the tech forums...... Cost is around $320.

4) I have the upgraded Saleen heat exchanger and it is well worth the money.....

5) Brent will likely prefer to tune your car for 93 octane but you can talk to him about this directly.... let him know what is most common in your area.

6) A driveshaft loop is always a good idea, that's for sure.

7) Save up money for a good set of performance tires- you will need them.

Thanks Tom a lot for your quick list and points - I is very useful for me

Just couple questions about clutch subject – Point 3/.
You are going to do 3+ along with a steel flywheel - Is that factory oem flywheel or you changing that for a new one? Which then if not secret?
”Hydraulic throw-out bearing from RAM+ do you mean this: ?
(http://www.lethalperformance.com/pag...-cylinder.html)
And generally maybe is worth to first burn out the stock clutch and then invest on a new one.

Point 4/
If I will decide to go With Oil Cooler Kit by Cobalt will that fit with Saleen Heat Exchanger upgrade together? Here is oil cooler kit installation guide http://www.mossmotors.com/graphics/p...ns/056-290.pdf


OK and now finall questions to you all about suspension mods connected with new power.
My suspension is stock now and I am not going to lower that now, it will be future step, but I need to make it a bit stronger to handle 485HP.

On my list is:
1/ 05-07 MUSTANG GT 7/8" REAR SWAY BAR BMR (http://www.brenspeed.com/sb023.html) or I should rather go with Steeda Competition Rear Swaybar w/ Endlinks (http://www.steeda.com/products/comp_...h_endlinks.php)
2/ Mustang GT Frame Rail Torque Box Brace Steeda (05-08) (http://www.brenspeed.com/555-5551.html)
3/ Mustang GT Billet Lower Trailing Arms Steeda (05-08) (http://www.brenspeed.com/555-4405.html)
4/ Saleen Series VI Supercharger Strut Tower Brace (05-09) (http://www.brenspeed.com/chtb1.html)
5/ Already mentioned above 05-08 Mustang Gt Two-Piece Driveshaft Loop Kit (http://www.fordracingparts.com/parts...tKeyField=8082)

Would you suggest anything else?
I am not sure about point 2 and which one take in point 1? – there is 150$ difference between them - what about handle?

I don't know if it will fit or not....... go with the upgraded heat exchanger first though for sure, atleast in my opinion. This has proven to be very beneficial.

2/ Mustang GT Frame Rail Torque Box Brace Steeda (05-08) (http://www.brenspeed.com/555-5551.html) Good idea.
3/ Mustang GT Billet Lower Trailing Arms Steeda (05-08) (http://www.brenspeed.com/555-4405.html) VERY, VERY good idea.
4/ Saleen Series VI Supercharger Strut Tower Brace (05-09) (http://www.brenspeed.com/chtb1.html) OK to do, but a little unnecessary IMO.
5/ Already mentioned above 05-08 Mustang Gt Two-Piece Driveshaft Loop Kit (http://www.fordracingparts.com/parts...tKeyField=8082) GOOD idea.

See above in BLUE.

I would stop there, and any extra funds that you have available, I would pocket them and put it towards a GT500 fuel system. The KB Boost a Pump will certainly work, but the GT500 system is the factory Ford system and provides increased reliability in my opinion. There is nothing worse than running out of fuel on a supercharged engine...... the GT500 system will ensure that you don't have problems.

Just question about above A/F auto meter. Do you need to buy Oxygen Sensor Kit for A/F Ratio Monitor http://store.summitracing.com/partde...?part=ATM-2244 or its already in a set with above auto meter or you can connect to oem O2 sensor?

This is my set up

lc-1 kit and a DB gauge

http://www.innovatemotorsports.com/products/MTS.php

You will need to place the O2 sensor in a bung before the cats (O/R H or X Pipe or weld one into the stock h-pipe).

I havn't heard a lot of good things about the Brisk Spark Plugs, Champion also makes a 1 pc. plug.

Tom is running a smaller pulley and a larger H.E. and pulls 450+ RWHP, I run a 3.6 pulley and get 430+ RWHP.

Ok I spoke with Seth from brenspeed I also spoke with a guy here in Poland who is quite keen on American muscle cars and superchargers and he will do the install in a future
Seth said with Stage 2 Saleen I do not need KB BAP and GT500 dual fuel pumps and stock one is enough for that application. But if I will have to much money maybe I will consider to buy KB BAP.
He said that my new Champion I pcs plugs should be ok as well.

I push then a trigger now for following things spending 2400$. Now I need to get them to Poland what will cost me about another up to 40% more uuh

Aeroforce Double Gauge - Blue/Black Display - Black Face/Silver Bezel - 05-08
Boost Sensor Kit 3bar
Cobalt A/F Auto Meter 6178
Triple Bullet Style Full A-Pillar Gauge Mount - Charcoal OE Finish - Coupe - '05-'08
Mustang GT Frame Rail Torque Box Brace Steeda (05-08)
Mustang BMR Front Bolt In Driveshaft Loop (05-08)
Mustang GT Adjustable 3rd Link Steeda (05-08)
Mustang GT Billet Lower Trailing Arms Steeda (05-08)
Oil Cooler Kit by Cobalt
MMR 7 Quart High Performance Oil Pan
MMR Performance Windage Tray

Now need to get money for a Saleen supercharger – hopefully this autumn-winter so will be ready on spring 2009.

Thanks all of you for your help.

Your mod list is very impressive indeed!!!! If i were you I would err on the safe side and do the KB boost a pump. You can't go wrong with it.

Unless you just want to buy all of those mods you don't need them for the power level you'll be at... But like Tom said they would be a good to have, or I would say "they wouldn't hurt". That kit should put you at about 430rwhp which is where i'm at. A good set of gauges ( wideband included), suspension/ tire setup ( lca's included), fuel system ( gt 500 included... lol), tune ( brenspeed included...lol) and colder plugs... Would get you off to a great start IMO.
